2. Description of Related Art
With the developments of display technologies in recent years, the resolution of display plays a key role. Generally, displays can be categorized into active light-emitting displays, such as cathode-ray tube (CRT) and light-emitting diode (LED) displays, and passive light-emitting displays, such as liquid crystal displays (LCDs).
Compared with conventional CRT displays, LCDs consume less electric power and occupy less space, and thus they have been the mainstream in markets of display. In operation, thin-film transistor (TFT) displays include driving units, such that voltage signals transmitted on data lines are inputted into liquid crystal displaying elements in order to activate pixels. The primary function of the driving units is to output required voltages to the pixels to control the twisting degrees of liquid crystals in the liquid crystal displaying elements. The driving units can be separated into source drivers and gate drivers. The source drivers are configured to arrange inputs of data, and the gate drivers are configured to determine the twist degree and the refresh rate of the liquid crystal displaying elements. However, the conventional gate drivers generally have the following drawbacks: 1. a size of border for metal wiring is difficult to shrink; 2. gate voltages outputted to TFTs are insufficient.
Accordingly, inconveniences and deficiencies apparently exist in the aforementioned gate drivers and are needed to be further addressed. To solve the aforementioned problems, in related arts, efforts to find the solution are tremendous and no suitable solution is completely developed. As a result, how to provide sufficient charging voltages (gate voltages) and reduce circuit layout area is one of the most important issues and also becomes an objective needed to be overcome urgently in the related arts nowadays.
